我在 github 上找到了 Unlock7 示例项目，现在我正尝试在显示音乐 Controller 时向背景添加模糊 (stackblur)，但我在编译时遇到此错误:

AXel-4:/var/mobile/unlock7 root# make package install

这是生成文件:

include $(THEOS_MAKE_PATH)/tweak.mk

感谢任何帮助。 谢谢! (对不起英语不好)

最佳答案

这是因为 TWEAK_NAME 和 BUNDLE_NAME 具有相同的值。 Makefile 应该是这样的:

export GO_EASY_ON_ME = 1
include theos/makefiles/common.mk

TWEAK_NAME = Unlock7
$(TWEAK_NAME)_INSTALL_PATH = /Library/MobileSubstrate/DynamicLibraries
$(TWEAK_NAME)_FILES = Tweak.xm UIImage+StackBlur.m
$(TWEAK_NAME)_FRAMEWORKS = UIKit CoreGraphics
include $(THEOS_MAKE_PATH)/tweak.mk

BUNDLE_NAME = Unlock7img
$(BUNDLE_NAME)_INSTALL_PATH = /Library/MobileSubstrate/DynamicLibraries
include $(THEOS)/makefiles/bundle.mk

after-install::
    install.exec "killall -9 SpringBoard"

BUNDLE_NAME 现在有一个不同于 TWEAK_NAME 的后缀。您可以为 bundle 使用任何其他名称。

根据新的包名称重新定义包在源中的路径:

#define kBundlePath @"/Library/MobileSubstrate/DynamicLibraries/Unlock7img.bundle"
